Impact crushers are a mechanical crushing machine that has a massive rotor, with rigidly fixed working bodies - replaceable hammers (beaters) made of wear-resistant steel.
They are used to crush large pieces of material by rapid rotation of the rotor; in this case, multiple impacts of the pieces of material occur first, then the material is thrown off and strikes against baffle plates or gratings, which leads to its destruction.
This process occurs repeatedly, as a result of which the material acquires the desired size.
Impact crushers are used for crushing soft, low abrasive materials such like lime, ores, coal, crushed stone, sedimentary rocks and more. Tensile strength at
Most often, impact crushers are used for the manufacture of crushed limestone rocks.
The crushed stone released from the unloading slot has a grain of an improved shape and a small proportion of flat (flaky) elements.
Although impact crushers have a narrow scope of use, they have a number of advantages:
Impact crushers are ineffective for crushing strong materials due to high consumption of fast-wearing crushing elements.
